[Pkg-utopia-maintainers] Bug#939221: avahi-daemon: occasionally goes out of memory and crashes

[Francesco Potortì]

Package: avahi-daemon
Version: 0.7-4+b1
Severity: minor

>From time to time (hours, days, weeks) I see in the logs that
avahi-daemon has crashed.  Adding to the strangeness is the fact that it
crashes again as soon as it restarts;
